more particularly to the class of ailtomatic siphons.

Ihe primary object of the invention is the provision of a siphonwherein water from a higher level will be delivered to a lower level, thus enabling mines to he freed from water, the siphon being novel in form to permit branching off the main siphon to any number of reservoirs, thereby assuring rapid transfer of the water from the higher level or levels.

Another object of the invention is the provision of a siphon of this character wherein the entire system can he readily and quickly tested to ascertain if. leakage is present therein. and in this manner determine the perfect \vorking'of the same.

A further object of the invention is the provision of a siphon of this character wherein the construction thereof is generally improved so that the same is assured of good service, and if any defects are present they can be readily located for repairs.

A still further object of the invention is the provision of a siphon of this character which is Simple in construction, thoroughly reliable and efficient in operation, and in expensive in manufacture and installation.

WVith these and other objects in view. the invention consists in the construction. combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing. and pointed ou in'the. claims hereunto appended.

In the drawing:-Figure 1 is a fragmentary side elevation of the device constructed in accordance with the invention, with a portion thereof in sectional elevation. Fig. 2 is a fragmentary plan view.

' showing the branches from the main siphon.

Fig. 3 is a plan of the complete siphon.

Similar reference characters indicate cor responding parts throughout the several views in the drawing.

Referring to the drawing in detail. the

siphon comprises a main supply pipe A, the

area of the cross section of which should equal the area of the cross sections of allthe branches hereinafter. mentioned. which is upwardly arched. and has at its highest point-a pressure tank B provided with a glass gage tube C o't'the usual type, while in the top 1s mounted a short pipe D for communication with the atmosphere. and

having a cut-off valve E, the. tank being united to the main siphon pipe A through the medium of a short pipe F which has therein a plug hand valve (i fo a purpose presently described.

On one end of the main siphon pipeA is 'mounted a reticulated strainer drum 10.

while within the end of the pipe is arranged an automatlc float valve 11 formed with an arm 12 carrying the usual ball float 13.

while at the opposite end of the said mainsiphon pipe A is an upturned or verticallv disposed discharge terminal pipe H which serves as a water seal, or it may be inserted in a small tank or reservoir. if desired.

which answers the same purpose to prevent the atmospheric air from enteringthe pipe during the period when the siphon is not in operation.

Leading from the stretch of the pipe A carrying the strainer 10 at opposite sides thereof are a plurality of branch pipes 15 in which are arranged the respective hand controlled valves 16 and the float operated valves 17. which latter are constructed identically with respect to the float valve 11 in the main siphon pipe. and these branches extend to the various water reservoirs in the mine, and have on their free. ends reticulated strainer drums 18 which are constructed correspondingly to the strainer drum 10 for filtering the water to free the same from coal atoms or other foreign matter, and thereby obviate any possibility of the choking of the siphon during the operation thereof.

The main siphon pipe spaced from the float valve 11 is provided with a hand controlled gate valve 19. and also connected with this end of the said pipe is a lead pipe 20 from a force pump 21 of any approved construction. having the inlet 22 carrying a certain the perfect working thereof the same can be accomplished by manipulating the valves in a manner presently described.

lVhen it is desired to test the system the valves E and G are opened in the respective pipes D and F, while the valves 16, 19 and 25 in therespective branches 1:) and main siphon pipe A are closed, and on actuating the pump 21 the siphon pipe A is filled with water by means of the said pump until such water begins to rise in the gage glass, then the said valve E is closed, whereupon continuous pumping of the water is carried forth into the system until there is a good pressure of air in the tank B, say. for example, twenty or thirty pounds or more, and finally the valve 24 is closed for permitting a close inspection of the entire sys tem to ascertain if there is any leakage therein, which may be readily discovered. If there are no leaks all valves, except the valves'E and 24, are opened, and the system is now active for its operation. The float valves are acted upon by the water for the opening of the main siphon pipe A and thebranch pipes 15 so that water will enter the same and escape at its lower end for displacing, the water'at the higher level, the siphon being adaptable to a great many purposes Where a device of this class can be used.

From the foregoing description, taken in connection with ,the accompanying drawing,

the construction and manner of operation of the device Wlll be clearly understood.

ing an upwardly arched main supply pipe, 40

a short pipe connected with the mam supply pipe at the highest point thereof and being vertically disposed. a pressure tank communicating with the said short pipe and having a vent leading to the atmosphere, a valve in said vent, a cut off valve arranged in the short pipe, one stretch of) the main supply pipe being in a plane ele rated with respect to the plane of the other stretch thereof, a plurality of branch pipes arranged in outwardly divergent relation to each other and communicating with the elevated stretch of the main supply pipe. strainers on the outer free ends of said branch pipes, float operated valves arranged in the branch pipes, a hand controlled cage valve arranged in each of the branch pipes spaced from the respective float operated valve, a force pump having connection with the stretch of the main supply pipe to which are connected the branch pipes, and a. cage valve arranged in the lower stretch of the main supply pipe.

In testimony whereof I allix my signature in presence of two witnesses.
